{'teeth': [3, 0, 0, 0], 'molars': [1, 0, 0, 0], 'incisors': [1, 0, 0, 0], 'premolars': [1, 0, 0, 0], 'canines': [1, 0, 0, 0], 'milk': [0, 0, 1, 2], 'child': [5, 2, 2, 8]}

The milk teeth, or primary teeth, are the first set of teeth that children develop. These teeth start to appear around 6 months of age and are usually fully grown by the age of 3-4 years.

Option 1: Incisors - These are the front teeth that are used for biting into food. Incisors are included in the milk teeth.

Option 2: Canines - These are the pointed teeth that are next to the incisors. Canines are included in the milk teeth.

Option 3: Molars - Molars are the teeth at the back of the mouth that are used for grinding food. However, in children of 3-4 years, the milk teeth may not include the molars yet. So, option 3 is the correct answer.

Option 4: Premolars - Premolars are the teeth that come after the canines but before the molars. These teeth are also known as bicuspids and are included in the milk teeth.
